Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES)

Puzzled by which inductively coupled plasma optical emission spectrometry (ICP-OES) is right for you? No Need to be! Leeman labs offers the widest configuration of ICP spectrometers to fit any applications!

In 30 years of supplying inductively coupled plasma (ICP) Spectrometers, we've learned no one ICP-OES is ideal for all applications. That's why Teledyne Leeman Labs offers you the broadest range of ICP Spectrometers available. Let us help you select the best instrument configuration for your sample types.

All our ICP Spectrometers are available in RadialAxial or Dual View Configurations, so you can choose the view that's best for your sample matrix.​

 Dual View

​A Dual View ICP is one where the instrument is able to view the plasma in both the axial and radial views. The system is an axial design that uses a mirror to observe the plasma from the side.

The advantage of the dual view system is that it combines the best features of the radial and axial views in one instrument: The dynamic range and freedom from interferences of the radial, and the improved sensitivity and detection limits of the axial.​

Characteristics of Dual Viewing
  • Superior detection limits
  • Very wide dynamic range when using both views
  • Dynamic range shifts lower with axial view
  • Tolerance to dissolved solids similar to that of a dedicated axial
  • IEI effects of dedicated axial can be eliminated by using radial view of DV option
Typical Dual View Applications
  • Wastewater
  • Soils
  • Fertilizers

 Axial View

Axial (or end-on) viewing improves on the sensitivity and detection limits of the radial view by about a factor of 10 or more depending on the element. This is accomplished by looking down through the plasma rather than across it as in the radial view. The dynamic view isn't changed but is shifted towards the lower concentrations. The improvements are best seen in a clean sample matrices.

The improvements in sensitivity and detection limits are not without drawbacks. An axially viewed plasma is much more susceptible to interferences especially when samples containing high levels of dissolved solids are analyzed. Additional interferences are encountered when alkali elements (Li, Na and K) are measured where results can be wildly inaccurate unless special precautions and sample pretreatments are performed. These interferences are known as Easily Ionized Elements.

Characteristics of Axial Viewing
  • Superior detection limits
  • Dynamic range shifts to lower concentrations
  • Less tolerant to dissolved solids than radial
  • Torch lifetimes shorten the dedicated radial
  • Beware of EIE interferences
Typical Axial Applications
  • Drinking Water (Method 200.5)
  • Boiler water in nuclear plants

 Radial View

The radially (or side-on) viewed torch is the original ICP view configuration. Until the mid '90's, it was the only view available. This view has the ability to measure both very high and reasonably low concentrations of elements in samples (known as "dynamic range"). This design is also capable of handling samples with high level of dissolved solids and is remarkably free of chemical interferences and easily ionized element effects (EIE). It is the radial view that established ICP as a dominant trace element technique.

Characteristics of Radial Viewing
  • Wide dynamic range
  • Excellent tolerance to dissolved solids
  • Negligible interferences and EIE effects
  • Typical radial detection limits
Typical Radial Applications
  • Wear metal in Engine Oils
  • Industrial materials such as brines and fertilizers
  • Biofuels

Buying your inductively coupled plasma optical emission spectrometry (ICP-OES) is only the first step! Combined with our responsive Customer Support Team and Application Experts, choosing your next  ICP Spectrometer from Teledyne Leeman Labs is the right decision!

With your application requirements in mind, we invite you to look at the ICP solutions that Teledyne Leeman Labs has to offer.​

 Prodigy7

Teledyne Leeman Labs has taken a radically different approach with the Prodigy7. Through years of effort, our team of highly specialized engineers and application chemists have produced an Inductively Coupled Plasma (ICP-OES) instrument in which superior analytical performance does not have to be traded off for any reason including price. And while the Prodigy7 offers all of the advanced capabilities some laboratories require none of them have to be purchased up front if not needed. They can be easily added later if needs change.​​


 ProdigyPlus

Prodigy Plus brings together the latest in solid-state detector technology and Leeman Labs' advanced high dispersion Echelle spectrometer to provide the most powerful ICP available today. Not only does Prodigy Plus provide superb resolution, stability and detection limits for reliable results, it also provides a wide variety of optional features that are guaranteed to enhance the capabilities of your organic analysis lab.​
